Teensy Loader Application

The Teensy Loader makes getting
code into your Teensy easy. Just press and release the reboot
button and the processor runs the HalfKay bootloader, which is automatically
detected. Teensy Loader lets you download your code and reboot to it.

Automatic mode downloads and reboots to your code the instant your computer
detects HalfKay. The latest version of your code is always used. Just
press the button and within 1 to 2 seconds your latest code is running!
